It has been highlighted again & again on this blog that performance of a CCTV Security Camera is not something which is totally dependent on the camera itself, which means, you cannot give 100 % credit to your favorite camera for its best resolution, and on the other hand you cannot even blame it for the low performance .
The show of CCTV Security Camera System is a team effort and is run by various components/modules in it playing their part and contributing to its overall performance. One such module is communication channel deployed for taking signals from camera at one place to the central monitoring station. We already discussed various types of topology employed in a CCTV System in our previous post for the case when communication channel is optical fiber network for larger distances. But there is more to it. Depending on the distance to be covered, technical expertise, budget available, there are n number of communication channels that can be used to make a CCTV System work in a premises.
